Objective This study compares different problematic eating behaviors (PEBs; objective [OBE]/subjective [SBE] binge‐eating and compulsive [CG]/noncompulsive [NCG] grazing) in relation to the severity of loss of control (LOC) and psychopathology. We also investigate LOC as a mediator between PEBs and psychopathology. Method This cross‐sectional study assessed a group of patients before bariatric surgery (n = 163), and a group of bariatric patients 12 months or more after surgery (n = 131). Face‐to‐face assessment: Eating Disorders Examination for binge‐eating episodes; Rep(eat) for grazing. LOC was measured by five questions answered in a 5‐point Likert scale. Self‐report measures: disordered eating, grazing, negative urgency, depression, anxiety, and stress. Results OBEs were reported by 26(8.8%), SBE by 29(9.8%), CG by 35(11.9%), and NCG by 36(12.2%) of patients. The different PEBs differed significantly in the severity of LOC (F(3,120)= 25.81, p
